2C Greases

Performance Lubricants

For Anti-Fretting Applications

Product Information
Krytox™ oils and greases are based on perfluoropolyether(PFPE) oils. Krytox™ 2C grease is made using Krytox™
PTFE and a non-melting thickener. The capabilityof the greases’ upper limit is determined by theevaporation or breakdown temperature of the oil. Thesesynthetic fluorinated lubricants are used in extreme
conditions, such as continuous high temperatures up to300 °C (572 °F) and higher temperatures for shorter

periods, depending on product grade limits. They are
nonflammable and safe for use in oxygen service. They
are chemically inert and are used safely around hazardous
chemicals. They do not damage plastics or elastomers
or cause corrosion to metals. They are commonly used
as lubricants in aerospace, automotive, industrial, andsemiconductor applications, as well as solving many otherroutine lubrication problems.

Krytox™

Performance Lubricants

Krytox™ 2C greases contain an oil-soluble additive thatis effective at preventing corrosion and reducing wear.
It also contains a micro-powder, boron nitride, extreme
pressure additive. Typical applications include those inpotentially corrosive atmospheres, where vibrationalor shock loading may be significant and an element will
spend more time experiencing mixed film or boundary
lubrication versus the desired full film or hydrodynamiclubrication.

Packing the Bearing

Typical Applications
Applications for Krytox™ lubricants are generally of a
critical nature, where temperatures in all industries arereaching extremes for conventional lubricants. Lubricants
are expected to be durable in the most aggressive
environments and are now often considered an integral
part of the design. Where failure of components is not anoption, whether because of durability, warranty, safety,
loss of productivity, or downtime, Krytox™ oils and greases
are the lubricant of choice in a wide range of industries
and applications.
Krytox™ oils and greases are silicone-free. They do notcontain any VOC materials or chlorine and are nothazardous to the atmosphere or ozone layer. They are
biologically and environmentally inert.

New unlubricated bearings often have rust-preventive
oils in them to prevent damage while they are in storage
before use. New bearings should be inspected for damage
and cleanliness before use. The greases or preservativeoils need to be removed when using Krytox™ lubricants.
Failure to do so could result in reduced bearing life.
Bearing life tests on uncleaned bearings have shown
reduced life in high temperature, high speed tests,
where the bearing was filled with a minimum amountof grease. The preservatives coat the metal surface toprevent rusting; so, they can also prevent the grease fromadhering, causing them to be thrown off by the action ofthe bearing. They could also oxidize and harden, creating
debris that will contaminate the grease.
Storage and Shelf LifeThe XP series of Krytox™ lubricants can develop an odor
and a slight amber/pinkish color over time. The XP series
has a three-year shelf life and a recommended maximum
operating temperature of 182 °C (360 °F). Testing has
shown that these products retain their anti-rust andanti-wear properties and perform well past the end of therecommended three-year shelf life. Keep product sealed
and store in a cool, dry place.
